Probability
=number of successful outcomes/number of possible outcomes.

A standard deck has 4 kings and 52 cards.

What constitutes a successful outcome is drawing a king.
The number of possible outcomes is the number of cards in a deck.

So use the definition given at the beginning to find the probability of success (drawing a king).
4/52
